3 Claims. (Cl. 100-232) This invention relates to improvements in balingpresses, and more particularly to such presses as are used for balingscrap metal of the general character set forth in my prior Patent No.Re. 23,737, granted November 17, 1953.

Baling presses of the character described and referred to in theaforesaid patent have heretofore been constructed of very heavy materialand have been mounted permanently in an installation, frequently in apit in the to accomplish the compressions necessary for compacting scrapmetal and metallic devices and therefore have required such heavy andrigid construction.

Frequently it is desirable to make the baling presses capable ofportability, to be moved from place to place.

This has not been possible heretofore except at sacrifice of some of theimportant elements of the press. For example, it has been necessary toremove the ejector if the machine is to be moved, or to omit it entirelyin order to make the press portable.

One object of the invention is to improve the construction of balingpresses to provide an effectively portable press which may be moved fromplace to place, when desired, without sacrificing either the sturdy,rigid structure of the press, or the provision of an ejector thereon,which ejector, nevertheless, always remains as a unitary part of thepress, without requiring its omission or removal, in the event that thepress is to be moved from place to place.

A baling press, as constructed heretofore, has had provision forcompressing the material into a bale of prede termined size anddimensions. Frequently, it is desirable,

however, to supply the baled scrap material in bales of smallerdimensions. This has not been possible with presses heretoforeconstructed, without materially reconstructing the compression chamberthereof.

. Another object of the invention is to improve the construction of thebaling press by providing for the compressing of the material intovariable sized bales which may be either large or small, as selectivelydetermined by the provisions in the press for such variation.

Still another object of the invention is to provide for an adjustment orvariation of the compression chamber and/or the plunger heads to varythe size of the bale ground. Such presses are subject to very greatpressures box for maximum sized bales; and

ice

or mounted thereon, spacer plates to reduce the overall width of thecharging chamber upon advancement of the main pusher head to the limitof its forward stroke. The side pusher head is replaced with one ofsmaller dimensions to operate between the face plate on the main pusherhead and the liner plate on the end wall, 'in the adjusted positions ofthese elements, whereby to compress the material into smallerdimensions.

If portability be desired, the press preferably is formed and mounted onskids so as to be moved thereon from place to place. The ejectorcylinder is located entirely above the bottom of the skids, preferablysuspended on a hanger, and being of a construction of the two-sleevedouble-acting type whereby it will operate. through a-sutficient stroketo push the bale out of the chamber of the box to the top thereof, sothat the formed bale may be pushed by the door off the rear ledge.

. This embodiment of the invention is illustrated in the accompanyingdrawings, in which:

Fig. 1 is a side elevaiton of a baling press embodying this invention;

Fig. 2 is an end elevation thereof;

Fig. 3 is a side elevation of the main pusher head provided with aspacer plate for forming a bale of reduced size;

Fig. 4 is a diagrammatic top plan view of the charging Fig. 5 is asimilar view in which the variations have been made for providing a baleof reduced size.

In this embodiment of the invention, the baling press is illustrated asmounted on supporting beams or skids, generally designated by thenumeral 1, having cross beams 2 connected therewith for supporting thecharging box 3. The latter is closed at the sides and ends in a mannerwell understood in the art, an example of which is set forth in myaforesaid Patent No. Re. 23,737.

The open top of the charging box 3 is adatped to receive the materialtherein to be compressed and to be closed by a sliding door 4 which isreciprocated by a hydraulic power device, the cylinder of which isindicated at 5. The door 4 is mounted on rollers 6 and 7 forreciprocating movement back and forth over the top of the terial thereinthrough the open top thereof upon withformed in the press as, forinstance, to provide a bale having the dimensions 6" x 6" x 16", orapproximately the dimensions of 10" x 12" x 16", which adjustment can beaccomplished quickly and readily whenever required. The 12" is variableanyway.

In accomplishing these objects, the invention may be constructed with acharging box having main and side plunger heads operatively mountedtherein in the usual manner. Where the maximum size of bale is to beformed, these plunger heads and charging box may be operated withoutvariation. However, if it be desired to reduce the size of the bale, theside plunger head is preferably removed. The main plunger head and theend face of the charging box have incorporated therein,

drawal of the door 4. The inner walls of the charging box are providedwith liner plates 12 and 13 extending along opposite sides thereof andbetween which a main pusher head 14 operates, being reciprocated by ashaft 15 connected therewith, connected with a suitable doubleactinghydraulic cylinder, indicated generally at 17 in Fig. 1.

The liner plate 12 extends to the end wall of the charging box, whichend wall is shown at 18 in Figs. 4 and 5. A liner plate 19 is securedover the face of the end wall 18 and extends transversely of the end ofthe charging box, throughout the area thereof.

The liner plate 13 does not extend entirely to the end of the chargingbox 3, but terminates short thereof at a point spaced appreciably fromthe liner plate 19, thus providing an opening through the side wall,which is generally indicated at 20, through which a side pusher head 21may operate. The side pusher head 21 is connected with a shaft 22thatextends to a piston in a double-acting hydraulic cylinder 23 (Fig.2) mounted at a side of the charging box 3.

When the material is dumped into the charging box 3, the pusher heads 14and 21 are retracted the full strokes of the hydraulic cylinders" 17 and23. Then, when the desired quantity of desired scrap material has beensointroduced in the usual way of operating such presses, the main pusherhead 14 is moved forward in the charging box for the initial compressionof the material; This main pusher head 'is provided with a face plate 24directed toward the material in the charging box to apply the'pressurethereto. The main pusher head 14 moves forward in such position withrespect to the opening 20 thatthe outer face of the face plate 24 willbe in direct alignment with the inner edge of said opening, as shown inFig. 4. 'Then,"while holding the main pusher head 14 in this position,the'side pusher head 21 is operated and moved from the position besidethe charging box 3 to the position indicated bydotted lines within thecharging box for the final compression of the bale. i t

If it be desired to eject the blade from within the charging box, anopening 25 is formed in the bottom thereof within which an ejector headis mounted, which preferably is hydraulically operated, as, forinstance, by the hydraulic cylinder shown at 26 in Fig. 2.

The parts are shown in Fig. 4 in the relation whereby the maximum sizedbale will be formed. If it be desired to form a bale of smaller size,the necessary adjustments or variations in the construction can beaccomplished very quickly and easily, as, for instance, within one totwo hours, to enable the same machineto be used to form bales ofappreciably smaller size. An example of variationin the size of bale tobeformed may be mentioned as a change from a bale having the dimensionsof x 12" x 16", which can be varied to a size of bale of -6" x 6" x 16".7

To accomplish'this change, the side pusher head 21 should be withdrawnand removed and an adjustment can be made easily and quickly at the endsof the charging box 3 and at the end face of the main pusher head, asshown in Fig. 5.

The face plate 24 of the main pusher head 14 'is removed and aspacerplate 27 is inserted between the face plate 24 and the main pusher head14. These'parts are secured rigidly together, as, for example, by meansof bolts shown at 28 in Fig. 3. It will be apparent that the same faceplate 24 is used, but is applied over the spacer plate 27. i

At the end wall 18, the liner plate 19 remains in the same position,butis covered by a spacer plate 29, and the latter in turn is supplementedby an additional liner plate 30. These parts are properly aligned witheach other and secured .rigidly in tight relation, as, for ex ample, byboltslike those shown at 28 in Fig. 3.

With the addition of the plates 27, 29 and 30, it will be apparent thatthe transverse width of the final compression chamber is materiallyreduced. A side pusher head-of smaller dimensions-is thereforeaccommodated in this reduced compression chamber, as indicated at 21 inFig. 5. The smaller side pusher head 21 will be operated; however, bythe same hydraulic cylinder 23 and through the same stroke as the sidepusher head 21,

but the axial length thereof may be varied as desired. Thus, theoperation of the modified pusher heads 14 and 21' will produce a bale ofreduced dimensions in the two directions illustrated in Fig. 5, butremaining of the same depth, since no adjustment of the depth of thecharging box has been indicated.

Inasmuch as the side pusher head 21' does not fill the entire opening20' between the inner face of the liner plate 30 and the adjacent edgeof the liner plate 13, a fill block is introduced, as indicatedat 31.This fill block 31 is held in place by a stop block 32 welded orotherwise secured to a plate 33 on the adjacent side wall the fill block31 to'the plate 33.

of the charging box 3. Bolts 34 are used for securing The fill-block 31should be of a size so as to register with the inner face of the faceplate 24 when the main pusher head 14 is in its forward position, aswill be apparent from Fig. 5.

These parts may be removed and replaced to provide for the larger orsmaller sized bales very simply and readily, with few additional partsand with very little labor. Thus, it is possible with the same balingpress to provide bales of either maximum or minimum dimensions, asdesired. a 1.

Where it is desired that the baling press be portable or movable fromplace to place, the sills or beams 1 preferably should be in the formofskids, as shown in Fig. 1. In that event, to avoid the necessity forremoval of the ejecting cylinder 26, the latter is preferably made of asmaller dimension than the space between the bottom of the charging box3 and the bottom facesof the skids 1. A telescoped two-sleeve ejectorcylinder 'may be used for this purpose, supported by a hanger 35 that issuspended from the bottom of the charging box 3 in the relationillustrated in Figs. 1 and 2. The cylinder 26 will have sufficientstroke in the telescoped cylin der thereof, to push the bale to the topelevation'of the rear of the charging box 3 where the door 4 can pushthe .bale off the rear ledge. By using a cylinder of 'the charactermentioned, mounted on the bottom of the charging box, with its lower endentirely above the bottom faces of the skids 1, the press may becompletely portable with the ejector intact, without requiring eitherthe omission of the ejector plunger or the removalthereof forportability.

While the invention has been-illustrated and described in oneembodiment, it is recognized that variations and changes may be madetherein without departing from the invention as set forth in the claims.l
